室内空气质量（IAQ）是一个重要的社会和经济问题。有几种设计策略可用于提供良好的室内空气品质。如果作为整体设计方法的一部分（强调整体的重要性和各部分的相互依赖性），控制通风、适当的设计和使用适当的健康建筑材料可以提供良好的室内空气质量。作为完整室内空气品质设计策略的一部分，吸湿活性材料（所谓的呼吸墙）可以帮助调节室内湿度，从而降低建筑表面真菌生长的可能性。本文讨论了室内空气品质的三种基本设计策略以及呼吸墙的作用。讨论了呼吸墙的物理特性，并概述了呼吸墙改善室内空气品质的方法。 本文描述了一个旨在探索低密度水泥粘合木纤维（CBWF）性能的研究项目。这项研究包括材料测试、全尺寸墙体的现场监测和计算机建模。本文介绍并讨论了这项研究的一些结果。通过计算和现场数据的支持，得出结论:采用整体建筑设计方法，室内空气品质可以大大提高。当与其他策略结合使用时，由蒸汽渗透性和高吸湿性材料制成的呼吸墙可以提高室内空气品质。单位:双引用:研讨会论文，佐治亚州亚特兰大，2001年

Indoor air quality (IAQ) is an important issue from both a social and economic point of view. There are several design strategies that can be used to deliver good IAQ. Controlled ventilation, proper design, and the use of appropriate healthy building materials can provide good indoor air quality if used as part of a holistic design approach (one that emphasizes the importance of the whole and the interdependence of the parts). As part of a complete IAQ design strategy, hygroscopically active materials (so-called breathing walls) can help moderate indoor humidity and thereby reduce the potential for fungal growth on building surfaces. This paper discusses the three basic design strategies for IAQ and the role of breathing walls. The physics of breathing walls are discussed, and the ways in which such walls can improve IAQ are outlined. A research program directed at exploring the properties of a low-density cement-bonded wood fiber (CBWF) is described. The research included material tests, field monitoring of full-scale walls, and computer modeling. Some results of this research are presented and discussed. Supported by calculations and field data, it is concluded that IAQ can be greatly improved by using a holistic approach to building design. Breathing walls made of vapor permeable and highly hygroscopic materials can enhance IAQ when used in conjunction with other strategies.Units: Dual
